In order that the vertically movable pin 9 may be secured within a predetermined opening of the rail 7 and for preventing the release of the fingers -15 from the rail, said pin is formed at a point beneath the guide sleeve 8 with a slot 18, while depending from opposite sides of the guide sleeve 8 are 7 lugs 1919 that also have slots therein in registration with the slot 18 in order that a sealf20"may be passed therethrough. Theyform of the invention disclosed 1n Figure 6 is substantially identical to the form disclosed in the other views Withthe exception of the fact that the upper plated end 13 of this lever 14" has pivotally attached to one side only one finger 15 similar in all respects to the fingers 15-15 in the otherform of the invention with the excep tion that thelower end thereof is provided with a depending untapered lug 17 for engagement within the openings of the rail 7 In this form of the invention when the pin 9 is raised, a swinging movement of the lever l will create a pull upon the fingersfor openingthe doorto an extent equivalent to the degree of movement of the lever, whereas on the other hand a reversal of movement of the lever will cause a push upon said finger 15 tormoving the door in a closeddirection to a similar degree.

Itwill thus be seen that have-provided a highly novel, simple, and efficient means for facilitating the opening and closlng of slidingcar doors, andthat is also adapted for permitting the door to be locked and sealed in partially sealed'or fully closed position, and even though I-have herein shown and described the invention as consisting of certain detail structural elements, it is nevertheless to be understood that some changes may be made therein without affecting the spirit and scope of the appended claims.

7 Having thus described the invention, what I'claim is: i i b i -1. In a sliding car door operator, a rail secured 'to the car beneath the door and ments onthe rail, whereby the door may be formed. throughout its length with abutments, alever pivoted to the door adjacent the loweredge thereof, a finger pivotedat its inner end to the upper pivoted end of the lever, a pawl formed onthefouter 'free end of the leverfor engagement with the abut moved to open or closed position by a swinging movement of the lever, and a slidingbolt o carried by the door for cooperation with the pivoted end of the finger for locking the same against swinging movement.

3. In a sliding car door operator, a rail secured to the car beneath the door and formed throughout its length with abutment-s, a

lever pivoted at its inner end to the 11 per pivoted end of the lever, a pawl forme on the outer free end of the lever for en agement wit-lithe abutments on the rail, w ereby the door may be moved to open or closed position bya swingingtmovement of .the

lever,'a sliding bolt carried bythe door-for cooperation with thepivoted end ofthe finger forlocking the sameagainst swingin movement, means carried by the pivoted en ofthe lever for. cooperation with the sliding bolt to lock the lever against'swinging move-i ment,-said last. mentioned means comprising a pair of ears extending laterally from the inner :face of the pivoted lever zen-opposite.
